Every organism needs energy for their survival and other metabolism of the cell. Some process requires energy in the form of different chemical molecules.
Adenosine triphosphate may be defined as the energy currency of the cell. The hydrolysis of ATP helps in the transportation of molecules and in the metabolism process of the body. ATP is used directly by the cell as an energy source.
The flow of individuals in and out of a populationintroduces new alleles and increases genetic variationwithin that population. Mutations are changes to an organism's DNA that create diversity within a population by introducing new alleles.
